- 3, 3 \hspace{1cm}
- 0, 3
- 6, 3 \hspace{1cm}
- 3, 6
Show Solution
The Correct Option is C
Solution and Explanation
For the coordination complex \([Co(en)_3]Cl_3\), cobalt (Co) exhibits a primary valence (oxidation state) of 3. The secondary valence, representing the number of ligand bonds, is 6, stemming from the three ethylenediamine (en) ligands present.
